Code Reading Verification
The CopyGuard™ monitors and scans all standard barcodes and is specifically designed for the converting and fulfillment industries. Used with a MS-9 code reader, scanning at 2000 reads per second, individual scanning trigger software guarantees 100% inspection of each carton. A 'Good Read', 'No Read' and 'No Match' output is indicated on the display screen.

Cartons with incorrect, unreadable or missing barcodes will automatically shutdown the machine or track the carton for automatic rejection. Set-up is kept to a minimum with a simple 'learn' barcode feature.
